The Muncie A20-A1010-HX31XUS or A20A1010HX31XUS is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. The shift cover rotates a full 360 degrees, and the rotatable pump flange simplifies plumbing layout. Increased clearance around the mounting area makes installation more straightforward. Tapered roller bearings extend PTO service life, and the enlarged output shaft diameter improves durability under sustained load. Gear geometry is optimized for noise reduction, and leak paths are reduced compared to conventional designs. The A20 Series accepts an EX Drive shaft extension and accommodates three housing arrangements. Call us to confirm the correct configuration for your application.
